2. Description of the Related Art Various inspections are performed on optical fibers after production to guarantee their quality. Among the inspection items, the transmission loss is measured by measuring the intensity of light emitted from one end of the optical fiber and the intensity of light emitted from the other end. For this reason, it is necessary that both ends of the optical fiber can be taken out while the optical fiber is wound on the bobbin.

FIG. 5 is an explanatory view of an example of a conventional bobbin. FIG. 5 (a) is a perspective view of the bobbin, and FIG. 5 (b) is a perspective view of a state where an optical fiber is wound on the bobbin of FIG. It is. The conventional bobbin has a simple structure composed of two flanges 31 and 32 and a body 33. Then, as shown in FIG. 5B, the winding start end 34 and the winding end 35 of the optical fiber A are taped inside the flanges 31 and 32, respectively, so that both ends can be taken out. The optical fiber on the winding start end 34 side cannot be extended long.

As shown in FIG. 6 (b), after winding several meters to several tens of meters from the winding start end by the lead winding part 38, the lead winding part 39 is shifted to the main winding part 39 via the slit 37 so that both ends of the optical fiber A can be easily connected. A bobbin with a structure that allows the necessary length to be taken out is adopted.

On the other hand, as the production volume of optical fibers increases, the automatic operation of optical fiber manufacturing equipment is becoming an important issue for increasing productivity. For example, in the case of a bobbin having an intermediate flange provided with a slit as described above, Japanese Patent Application Laid-Open No. 64-38379 discloses a method for automating a work over a slit, which was conventionally performed by temporarily stopping the running of an optical fiber. As shown, improvements have been made such as providing an automatic slit overriding mechanism.

[Problems to be Solved by the Invention] However, in order to further promote automatic operation, not only the overcoming of the slit, but also the terminal processing of the optical fiber wound on the bobbin, which is currently performed manually, is also automated. Is desirable. To this end, an automatic optical fiber cutting device and a tape sticking device are necessary in terms of equipment, but since both are developed in other industrial fields, they do not particularly hinder automation promotion.

However, since the bobbin having the conventional structure as shown in FIGS. 5 and 6 is not originally designed in consideration of automation, it uses an already-developed automation equipment, particularly an automatic tape attaching device. In order to achieve the automation of terminal processing, there are the following obstacles.

[0008] The end of the optical fiber is generally fixed to the bobbin flange with tape at both the winding start end and the winding end. However, in a conventional bobbin, as shown in FIGS. Since the starting end and the winding end are respectively stopped by different flanges, it is difficult to stop by one automatic tape application device.

[0009] The winding length of the optical fiber is not always constant, and often differs for each bobbin. At this time, as shown in FIG. 7, when the winding length is small (FIG. 7A) and when the winding length is large (FIG. 7B), the position where the tape of the optical fiber terminal is applied is different. Is difficult to determine by machine.

[0010] The usual tape applicator has a structure in which a hand sandwiching the tape at the end extends and presses the tape at a target position, as shown in Figs. 5 (b) and 6 (b). If the optical fiber terminal is inside the flange of the bobbin, there is a risk that the hand may come into contact with the bobbin when the hand is carried. In particular, in the bobbin shown in FIG. 6B, it is necessary to insert a hand for applying tape in a narrow space between the intermediate flange and the flanges on both sides. Can not.

In the drawings, reference numerals 1 and 2 denote bobbin flanges, and reference numeral 3 denotes a trunk. One of the flanges 2 is provided with two slits, one of which is a deep slit 4 whose groove reaches the body 3, and the other is assumed in an actual use state of this bobbin. The shallow slit 5 is located outside the maximum winding diameter B of the optical fiber A.

The optical fiber A is wound on the body 3 through the deep slit 4 after the winding start end 6 is stopped outside the flange 2. The wound optical fiber A is further passed through the shallow slit 5 and the flange 2.
And the winding end 7 is stopped in the same plane as the winding start end 6. As a method of passing through the slits 4 and 5, for example, as shown in JP-A-64-38379, after approaching the slit with a sensor, the optical fiber A can be pushed out by a guide bar or the like and passed over. .

(A) to (C) or (A) to (C ') of FIG.
Since the groove of the shallow slit 5 is located outside the full winding diameter B of the optical fiber A as shown in FIG. 3, when the winding length of the optical fiber is small (FIG. 3C), when the winding length is large. (FIG. 3
In any case c), the position where the optical fiber A exits the flange 2 through the shallow slit 5 is always a fixed position regardless of the winding length. Therefore, when this bobbin is used, if the position of the tape application is determined first, there is no need to adjust the positioning thereafter. Therefore, the terminal treatment of the optical fiber can be easily performed only by installing the tape attaching device beside the winding machine. In this case, the initial positioning can be easily determined by adjusting the feeding length of the tape application hand 21 and the position of the upper guide roller 22.

FIG. 4 shows, as a comparative example, a case where the groove of the shallow slit 5 is located inside the full winding diameter B. In this case, the position 23 where the optical fiber comes out of the flange 2 when the winding is close to full winding goes outside the position 24 when the winding amount is small, and the winding end end may be stopped at the same position. Since it becomes impossible, a sensor or the like for terminal position detection is separately required, which greatly hinders automation.

In the bobbin of the present invention, the positions of the two slits may be anywhere. However, if they are too close, there is a possibility that the stop position of the winding start end and the stop position of the winding end may overlap. Therefore, if the two slits are located at a position 90 degrees or more of the flange across the shaft hole, desirably 180 degrees as shown in the figure, that is, if they are present on opposite sides, they may interfere with each other when processing the terminal. It is convenient. Further, if the outer surface of the flange 2 for fixing the tape is smooth, the tape can be more easily attached.

FIG. 2 is a perspective view of another embodiment of the bobbin according to the present invention, in which an optical fiber is wound. An ordinary optical fiber bobbin requires a lead winding portion for keeping several meters to several tens of meters from the winding start end for characteristic evaluation.
FIG. 2 shows a specific example in which such a lead winding portion is provided.

As shown in the drawing, the lead winding portion 19 and the main winding portion
Two slits 14 and 15 are provided in the intermediate flange 12 separating 20, and the terminal processing of the optical fiber A is performed on the outer surface (lead winding side) of the intermediate flange 12. At this time, in order to prevent the hand of the tape applicator from hitting the flange 18 outside the lead winding portion 19, the outer diameter of the flange 18 is desirably smaller than the intermediate flange 12, and the optical fiber of the lead winding portion 19 is It is most desirable to have a minimum height that will not scuff. With such a structure, the approach of the tape application hand becomes very easy, and the optimal tape application position can be easily determined even on the bobbin with the lead winding portion.
